Can we add:

import os

def _term_width():
    """ Simple terminal width, limit to 20 chars. and make 0 == 80. """
    if not hasattr(urlgrabber.progress, 'terminal_width_cached'):
        return 80
    ret = urlgrabber.progress.terminal_width_cached()
    if ret == 0:
        return 80
    if ret < 20:
        return 20
+    if os.environ.get("YUM_WIDTH") > 0:
+        return int(os.environ.get("YUM_WIDTH"))
    return ret


To the /usr/share/yum-cli/output.py file.

When I do yum list > /tmp/yum_mylist.list  the column width goes to 80.  I want to be able to set it.

I'm not a python programmer so the above was just a quick hack.
